I have a Dell Inspiron N5010 that gives a Dell beep code of 4, that means the ram is bad. I have checked the ram and it works fine (My Ram is Good Nothing Wrong with it). So why would my Laptop keep giving that code? I'm running Windows 10 Pro it has a new LCD and New 302 GB Hard drive New CMOS battery and 8 GB's of New Ram. This laptop worked fine till the LCD messed up and after I replaced it I can't get it to work Powers up but has a black screen and gives the 4 beep code.
